%X The structure of the title complex has been determined by a three-dimensional X-ray analysis. Triclinic crystals in space group P&#299; have lattice parameters a 7.0912(8), b 7.692(2), c 19.119(3)&#506;, &#945; 87.09(2),&#946; 84.01(1),&#947; 82.72(1)&#176;, Z 2. The structure was solved by means of direct methods and refined by full matrix least squares to R 0.039 and Rw 0.035 for 1671 observed reflections. Almost parallel tetracyanoquinodimethane (tcnq ) and pyridopyrroloquinoxaline molecules are stacked alternately along the a axis. Differences in C-C distances for the complexed  tcnq molecule suggest a certain amount of charge-transfer interaction between donor and acceptor molecules.
